Rain Tire Questions
- Thread starter ATTS
- Start date
There are tire reps on track, they can tell you tire pressures, give you advice on what tires to use and if you should use warmers or not in the rain.
Do not ask Dunlop advice to your Bridgestone rep and vice versa since tires are not all the same and one piece of advice can very differently among brands
On a different topic, have you ever thought about doing this so you don't have to safety wire every time you take your tires off
This is my old bike but the new one is about the same or better

I'm guessing each brand has their own recommendations regarding their wet tires. I remember running at Nationals on Pirelli and it was recommended you run your warmers for a half hour. I regularly run Dunlops and Sandy recommends no warmers although he has mentioned that you can run them if you like as it won't make a huge difference. Never run warmers on Dunlop rains....
Okay, cool, so now we have the answers for the big 3.
Bridgestone, no warmers.
Dunlop, no warmers.
Pirelli, warmers @ 65°C
But then Dave was the rep for Dunlop at Soar and he himself used warmers on rain (I believe)
Damn it, I will strive to do betterToo ambiguous for GTAM I'm afraid. LOL
I say you come racing this weekend, we will put you out there with warmers for 30 min and we will send Carboncat without warmer - Whomever crashes is the loser of the argument
Who's arguing? Anyway that's not fair. If it's about crashing I'd rather go against you.
That's not to keep them cold, rather, they do that to keep them from overheating. Two distinct temp ranges. Tires will operate best within a certain "temperature window" too cold, no grip, too hot, greasy. Dry slicks operate best at an elevated "operating range" while rains will operate best at a lower window.
Pre-heat to get into that window (in theory), run through puddles and off-line where there is more moisture to keep the tire from overheating on a drying track (with an ever-growing dry-line developing)
That's in car racing tires, I'm sure some of that translates to 2-wheels.
I was joking, I really don't care - Slow day at work.Who's arguing? Anyway that's not fair. If it's about crashing I'd rather go against you.
I was going to get into that put I decided not too, glad you did
Plan to do something similar eventually but it is a bit harder on my bike due to recessed fittings etc.
I know me too, but I'm out now and just bought some bacon to make turkey bacon ranch sandwiches for tomorrow. LOL
It was +2 that day with flurries circulating in the air, who knows maybe he was on Pirelli's :agave:
Here we go.
So technically For top caliber riders-You use warmers on a rain tire. Set it at 80 C and heat soak the heck out of it.
You want to heat the rim up to about 40 C. The tire will not produce it's own heat for about two laps. So the rim now becomes the heat sinc for the
two laps the tire is building heat.
Real world. Most guys go slow for the beginning of the session or race and get quicker as they get more comfortable. SO,,,, if you are an average rider/beginner rider and you use warmers here is where your problem will be. The tire is hot and as you get faster the tire will get colder. You "assume" your tire will maintain the same grip and probably will crash out about 4-5 laps in.
So most tire reps will have two scenarios. One for top caliber riders and one for not so top caliber riders.
If you use warmers you will have to adjust your riding as the tire changes temp. Or you will have to ride that tire hard to keep it hot.
A rain tire will operate on average around 35 C on a wet track with the tire throwing up a spray,,IF you are working it.
If you are a beginner and do not use warmers the tire will rise in heat as you get more comfortable. Your tire will stay more constant and this is the best application for most beginner riders.
This is also the best for riders that do not ride much in the rain. To be a good rain rider you must ride/practice in the rain. If you do not you most likely will fall back to the beginner category regardless of how fast you go in the dry.

Okay...that was useful. Thanks John!
Also for those that wish to use warmers,,do not get them wet. Getting them wet will shorten the life of the connections inside.
A little dampness on the outside is fine with most warmers,but just be sure to not let it get too wet.
